Question

An agriculturist plants legumes, which host the bacterium Rhizobium in their roots nodules for nitrogen fixation. How will these legumes enrich the soil?

Answer 1

In the root nodules, nitrogen fixation occurs between the bacterium Rhizobium and legumes in a symbiotic relationship. Nitrogen fixation is a process where atmospheric nitrogen is converted into ammonium. Ammonium is a fertilizer for the soil. Therefore, soil is fertilized and enriched.
